EYELETlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No.427,340, dated May 6, 1890.

Application filed July 27, 1889. Serial No. 318,888. (No model.)

T0 to whom it may concern:

Be it known that I, FRANK W. MERRIOK, of Boston,in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Eyeleting-Machines, of which the following is a specification.

This invention relates to eyeleting-machin es of the type shown in Patent No. 272,382, granted February 13, 1883, to L. D. Hawkins, said machine being organized to punch eyelet-holes in a boot or shoe upper or other article, insert an eyelet in each hole, and upset said eyelet. The said machine has a laterally-movable top set, which co-operates with a bottom set or finger in upsetting the eyelets, and is also utilized as a feeding device to feed the work, the finger of said top set being inserted in a hole punched in the work by a punch located at one side of the point where the eyelets are inserted, and then moved laterally to bring said hole to position to receive an eyelet.

The present invention has for its object to provide a machine of the kind shown in said Hawkins patent with improved devices controlled by the operator for moving the punch and its bed away from the point where the eyelets are inserted, thereby increasing the space between the holes, and at the same time correspondingly increasing the lateral movement of the top set or feed and stopping the feeding of the eyelets, so that the operator can, by depressing a treadle, arrest the feeding of the eyelets and cause the holes not supplied with eyelets to be made at greater distances apart than usual for the reception of lacing studs or hooks at theend of a series of eyeleted holes.

To these ends my invention consists in the improved devices which I will now proceed to describe and claim, in connection with the principal parts of the machine as shown in the said Hawkins patent.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a side elevation of an eyeleting-machine provided with my improvements. Fig. 2 represents a top View of the same, the eyelet-box being removed and the raceway leading therefrom being shown in section. Fig. 2 represents a top view of the punch-lever holder or carrier detached. Fig. 3 represents a section on line 00 m, Fig. 1. Fig. 4: represents an elevation of the opposite side of the machine from that shown in Fig. 1.

The same letters of reference indicate the same parts in all of the figures.

In the drawings, a represents the supporting-frame of the machine having a vertical socket or bearing, in which is journaled a vertical stud Z), having at its upper end a head I), to which is pivoted at d the top-set lever c. the top set c',which has the feeding-finger c. The top-set lever c is adapted to oscillate horizontally to feed the work by the turning of the stud in its bearing.

e represents the lever which carries the punch c, said lever being located beside the top-set lever c, and pivoted at f to cars on a holder or carrier g, the forward end of which supports the bed or block g, on which the punch descends in punching holes in the work.

The top-set lever c and punch-lever e are oscillated vertically and horizontally by the mechanism shown in the said Hawkins patent, to which reference maybe had for afuller description. The two levers are oscillated laterally in unison and oscillated vertically by independent means, so that after a hole To one end of said lever is attached has been made by the punch the top set and I punch are moved laterally while raised away from the point where the eyelet-raceway It delivers the eyelets to the fingerql on the bottom set j until the top set is over the hole last punched. The top set then descends until its finger c enters said hole, and then moves laterally back to the point where the eyelets are delivered, all as described in said Hawkins patent.

The holder or carrier to which the punchlever e is pivoted, is provided with an annular or ring-shaped ear or socket g Fig.

which surrounds and is adapted to oscillate upon the stud b,supporting the top-set lever, so that said stud constitutes a pivot or center on which the punch-lever holder and punchlever are adapted to oscillate independently of the top-set lever. The punch e and its bed 6" are therefore adapted to be moved toward or from the top set by the turning of the annular ear or socket g on the stud Z).

It will be observed that the stud Z) is the center on which the top set oscillates in unison with the punch in making its work-feeding movements, and is also the center on which the punch swings independently in varying the distance between it and the top set. It will be seen, therefore, that the in dependent movements of the punch to vary the spaces between the holes does not throw the punch out of the are or curved path in which the top set moves laterally, the punch always remaining in said are or path, so that the holes made byit are always in position to receive the finger of the top set. I desire to lay especial stress upon this feature-via, lateral swinging of the top set and punch on one and the same center or pivot-because I am aware that it has been proposed heretofore to swing the punch-lever holder on a pivot or center located at one side of the stud b, which serves as the center or pivot on which the topset lever swings laterally. Such an arrangement would be fatally defective, however, because of the said independent centers or pivots, which would necessitate the movement of the top set and punch in different arcs or paths, so that the holes made by the punch would not coincide with the top set under all adjustments of the punch. This objection is entirely overcome by my arrangement of the top set and punch on the same center or pivot.

I have here shown as the means for adjusting the punch toward and from the top set a rock-shaftm, journaled in bearingsin ears or lugs n n on a plate 0, which is attached to and oscillates with the stud b, said rock-shaft having two arms 19 q, a link 7" connecting the arm q with the rear end of the punch-lever holder 9, a rod 3 connecting the other arm 19 with a lever t, which is pivoted at one end to an ear u on the supporting-frame, and is connected at its free end by a rod to with a footlever or treadle; lrVhen the treadle is depressed, the rock-shaft m is turned so as to move its arm q in the direction indicated by the arrows in Figs. 2 and 3, and thereby cause said arm through the link 7' to swing the punch-lever holder andthe punch-lever on the stud or center 1) in the direction required to move the punch away from the top set. The punch remains in the position to which it was moved, as last described, until the treadle is moved in the opposite direction or depressed at its opposite end by the operator, the punch being thereby returned to its normal position.

The plate 0, which supports the rock-shaft m, is provided with an ear Fig. 3, which surrounds the stud b, and is firmly attached thereto by a set-screw or other suitable means. The arm q and the rear end of the punchlever holder or carrier are provided with projections 2 2, having rounded ends which fit loosely in corresponding cavities in the link 0".

The lateral throw or feeding movement of the top set is varied to correspond with the adjustment of the punch by the following devices:

3 represents a rock-shaft which extends crosswise of the frame a and is journaled in a bearing therein. To one end of said rockshaft is attached an arm 4, which is connected by a rod 5 with the treadle-operated lever 25. To the other end of the rock-shaft 3 is attached an arm 6, which projects upwardly and bears at its upper end against a detent '7, which is pivoted at S to the rear end of the top-set lever c. The free end of said detent 7 (which bears against the arm 6) is offset and provided with a bearing-screw 9, which is normally held by a spring 10 in position to strike one end of the yoke 12, in which the top-set lever oscillates laterally and by which it is oscillated vertically, as described in the Hawkins patent. WVhen the punche is atits normal distance from the top set, the rockshaft 3 is held in such position that its arm 6 permits the screw 9 in the offset end of the detent '7 to strike the end of the yoke 12, as shown in Fig. 1, and thus limit the lateral movement of the top-set lever, said yoke having no lateral movement and constituting a stop which, in conjunction with the detent 7 and its bearing-screw 9, limits the lateral movement of the top set away from the point where the eyelets are inserted and permits only the normal movement of the top set corresponding to the normal distance of the punch from the top set. vVhen the punch is moved away from the top set by the depression of the treadle and lever t, as above described, the rock-shaft 3 is turned by its described connection with the lever t, and the arm 6 of said rock-shaft is thrown forward and caused to displace the detent 7, so that its bearing-screw will not strike the yoke 12 when the top-set lever is moved to carry the top set away from the point where the eyelets are inserted. The top-set lever is therefore moved in the direction last indicated until it strikes an adjustable stop-screw 14, as in the machine shown in the Hawkins patent, so that the movement of the top set may be made by a suitable adjustment of said screw to correspond exactly to the adjustment of the punch. The feeding of the eyelets is stopped when the punch is moved away from the top set by means of the sliding bar 15, which is fitted to slide on studs 16 10 on the supporting-frame, and is engaged with one arm of a bell-crank lever 17, which is pivoted at 18 to the frame of the machine, and is connected by a rod 19 with the lever t. The depression of the lever t turns the bell-crank lever 17 in the direction required to force the bar forward and cause it to arrest a stud 19,which projects laterally from the spring-supported finger 2' in the hot- IIS tom set, said finger being thereby prevented from entering the eyelet-raceway and picking an eyelet therefrom when the bottom set rises.

Means similar to those above described for arresting the fingert'to stop the feeding of the eyelets are shown in Letters PatentNo. 325,07 7 to L. D. Hawkins, August 25, 1885; but said means are not shown in that patent as oper atin g con j ointly with the punch-adj usting and feed-regulating devices.

It will be observed that the operator is enabled by a single movement of the treadle to arrest the feeding of the eyelets, move the punch away from the top set, and displace the arm or stop which limits the feed movement of the top-set lever.

My invention is not limited to the details of mechanism here shown, and the same may be variously modified without departing from the spirit of the invention.
